Insiden terjadi ketika start-up isomerization unit, raffinate splitter tower meluap. Pressure relief device terbuka yang menyebabkan  flammable fluid keluar dari blowdown stack yang tidak dilengkapi dengan flare. Keluarnya fluid ini menyebabkan ledakan dan api. Fatality terjadi di kantor yang dekat lokasinya. 43.000 orang penduduk diperintahkan tetap didalam ruangan dan ledakan mengakibatkan rumah-rumah dalam radius ¾ mile dari refiney rusak.

Differential Pressure Level Transmitter Defect

Every liquid in storage tank will have hydrostatic pressure equal to the height of the liquid. With an assumption that the liquid has constant density. The DP level transmitter indication is a measure of the head pressure in the level of the tank whose level is to be detected. Head Pressure, DP, is calculated as DP = (Height).(Specific Gravity).

For example, let's say  50% level is displayed in the control room, the specified SG = 0.8. The DP transmitter is actually measure a differential pressure (50%)*(0.8) = 40 units of the differential pressure.

Gas Processing Unit Summary

Produced wellhead gas is wet, saturated with heavy hydrocarbons and contained with salt and sand.
Gas Conditioning Unit varies from a small station that handle 10 million SCFD to a big station that process 500 Million SCFD.

Wells scattered throughout the remote regions, and then carried by export line to the processing unit. Liquid are separated from gas. The liquids consist of salt water and condensate. The condensate is collected to oil refinery, where the condensate is blended into gasoline. The water is removed and then injected back into the ground in disposal wells.
